Summary
Built in 1962 by the USDA NRCS, this earth dam stands at a height of 32 feet and has a storage capacity of 278 acre-feet. With a drainage area of 0.71 square miles, it serves to mitigate potential flooding along the TR- Grays Creek, protecting the surrounding city of LaGrange.
Managed by the Mississippi Department of Environmental Quality, this dam is state-regulated and undergoes regular inspection and enforcement to ensure its structural integrity. Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level due to its age and condition assessment being not rated. While it currently has uncontrolled spillways and outlet gates, the dam plays a crucial role in safeguarding the local community from flooding events, highlighting its importance in water resource management and climate resilience efforts in the region.
As a key piece of infrastructure in the Memphis District and owned by the local government, the Grays Creek Watershed Structure G-6-05 Dam serves as a critical component of flood risk reduction efforts in Benton County, Mississippi. With its earth dam construction and buttress core design, this dam exemplifies the partnership between federal agencies like the Natural Resources Conservation Service and state regulators in ensuring the safety and protection of nearby communities. As climate change continues to escalate the frequency and intensity of extreme weather events, the resilience and maintenance of structures like the G-6 Dam 5 are essential in mitigating the impacts of flooding and safeguarding water resources for future generations.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
